Remote start/stop cable compatibility between Preston controller and RED Epic cameras

ما توصّل إليه النقاش
- The RED Epic camera requires a 3.3 volt signal sent through the coincide port to trigger recording, making simpleميكانيكيal cable solutions insufficient.
- Preston developed a dedicated start/stop cable for Epic cameras that connects to the white BNC connector on RED's medusa breakout cable, costing approximately $210.
- The medusa breakout cable from RED (model 3BNC-TO-00) is required when using Preston's Epic cable, adding approximately $100 to the total cost of the remote control solution.
- An alternative workaround involves building a battery-powered box with a toggle switch and BNC connectors to manually trigger recording through the red pigtail breakout cable, though this method proved unreliable in multi-camera shooting.
- When using GigE cables that link multiple Epic cameras together, the start/stop command can be transmitted through the cable connection between cameras rather than through the dedicated sync port.
- Third-party manufacturers, including Panavision London and independent cable makers, have successfully produced Preston-to-Epic start/stop cables.
- The fragile RED pigtail breakout cable required frequent replacement in field use.

- Some users reported inconsistent performance with homemade start/stop solutions, particularly in multi-camera setups where one camera might start or stop independently.
- The battery-powered workaround solution required monitoring battery voltage to prevent sudden power loss during shooting.
- Later users reported that availability and standardization improved after initial frustrated discussions, suggesting solutions evolved during 2011.
- The GigE alternative solution only works when cameras are physically linked via GigE cables, limiting its applicability to multi-camera shoots.
